Since this is a collector's forum, gonna post up the description of the deluxe edition:

Exclusive to the Muse webstore. Tri-fold vinyl packaging, containing the vinyl, CD and DVD, plus 2 exclusive art prints. DVD includes live performances of new songs from 'Drones' filmed during the Psycho UK Tour, as well as additional bonus studio footage. Includes a unique code to download the MP3 digital album on release date.

EDIT Just got confirmation of my order and a link to Psycho! Looks like they're working through it then. ---Sent a message to the store. We're far from the only ones with problems as well. Looks like anyone who's tried to order from the official shop has been unable to - wouldn't be a problem if the deluxe version wasn't exclusive to it!
